It has also been producing great amounts of waste with high-polluting level, which are commonly loaded into soil as fertilizer in order to increase soil fertility and provide higher crop yields. Such wastes can cause environmental problems when managed improperly, such as loss to soil fauna, an important constituent of soil. Thus, this study aimed at evaluating the tolerance levels of soil fauna by applying different swine wastewater (SWW) doses and the effects on abundance and diversity of meso and macrofauna organisms. The trial was carried out in Campo Bonito-PR, in an agricultural area that has been submitted to a non-tillage management for 13 years. Twenty one 25 m2 plots were set where corn, black oats and soybeans were cropped in different periods. Seven treatments were recorded as: 0, 50, 100, 150 and 200 m3 ha-1 from swine wastewater from a lagoon and there was a treatment using chemical fertilizers, according to the agronomic recommendations for each crop. The seventh treatment corresponded to the parts that were prepared in a remaining native vegetation area. Soil fauna was evaluated by the Tropical Soil Biology Fertility (TSBF) method, Berlese-Tullgren extractor and Pitfall traps. The collected organisms were classified based on their orders and results were evaluated by multivariate statistics, according to the correlation analysis (CA) technique, repeated measures indexes and indexes of Shannon diversity, Pielou evenness (Equitability) and richness of groups. The relation between fauna ecology and soil chemical properties was determined by canonical correspondence analysis (CCA). According to the results, it was observed that the application of swine wastewater/ slurry, stored in lagoon, has affected in a negative way the soil fauna when it received doses greater than 100 m3 ha-1, even though such dose has promoted greater similarity in abundance of organisms with the forest area. It was found out that the sampled orders characterize the forest area according to the simulated conditions: Collembola, Hymenopeptera, Araneae, Diptera, Acari, Hemiptera, Diplura, Protura and Oligochaeta, while Coleoptera order characterized the agricultural soils that are fertilized with swine wastewater. The results also showed that the soil fauna has its abundance affected by season and chemical composition of soil. / A suinocultura é uma prática econômica comum na região Sul do País, incluindo a região Oeste do Paraná, todavia, gera grande quantidade de dejetos, com elevado poder poluente. Esses são, comumente, lançados ao solo como fertilizantes; aumentam a fertilidade dos solos, proporcionam maior produtividade das culturas, embora possam trazer riscos ao ambiente quando manejados de maneira inadequada, tais como prejuízos à fauna edáfica, importante constituinte do solo. Por essa razão, foi estabelecido como objetivo deste trabalho avaliar os níveis de tolerância da fauna edáfica pela aplicação de diferentes doses de água residuária da suinocultura (ARS) e os efeitos sobre a abundância e a diversidade de organismos representados pela meso e macrofauna. O experimento foi conduzido no município de Campo Bonito PR, em área agrícola submetida ao manejo de plantio direto há 13 anos. Foram instaladas 21 parcelas experimentais de 25 m2, nas quais foram cultivados milho, aveia e soja em períodos distintos. Foram avaliados sete tratamentos: 0, 50, 100, 150 e 200 m3 ha-1 de água residuária da suinocultura proveniente de esterqueira e um tratamento utilizando fertilizantes químicos, de acordo com as recomendações agronômicas de cada cultura. O sétimo tratamento corresponde às parcelas instaladas em área de vegetação nativa remanescente. A fauna edáfica foi avaliada pelo método do Tropical Soil Fertility Biology (TSBF), extrator de Berlese-Tullgren e armadilhas Pitfall. Os organismos coletados foram classificados em nível de ordem e os resultados obtidos avaliados pela estatística multivariada, de acordo com a técnica de análise de correlação (CA), índices de medidas repetidas e índices de diversidade de Shanon, Equitabilidade de Pielou e Riqueza de grupos. A relação entre a ecologia da fauna e os atributos químicos do solo foi determinada pela análise de correspondência canônica (ACC). De acordo com os resultados obtidos, verificou-se que a aplicação da água residuária de suinocultura armazenada em esterqueira afetou negativamente a fauna edáfica em doses superiores a 100 m3 ha-1, porém a dosagem de 100 m3 ha-1 favorece maior semelhança em abundância de organismos com a área de mata. Verificou-se que, as ordens amostradas a seguir caracterizam a área de mata sob as condições avaliadas: Collembola, Hymenopeptera, Aranae, Diptera, Acari, Hemiptera, Diplura, Protura e Oligochaeta, enquanto a ordem Coleoptera caracteriza as áreas agricultáveis e fertilizadas com água residuária da suinocultura. Os resultados encontrados demonstraram ainda que a fauna edáfica tem sua abundância afetada sazonalmente bem como pela composição química do solo.

Generally, on the most production systems, the nutrition offer for the plants is made by chemical fertilizations that represents majority of the production costs. One alternative to reduce the costs and to provide qualitys nutrients is by the waste animals utilization. The aim of this study is evaluated the harnessing nutrient level of the residues extracted by crambe and its productive performance after the crop bean fertilizated with different doses application of poultry litter, pig slurry and chemical fertilization. The experimental area is located at the Experimental Station of the Agronomic Institute of Paraná, in Santa Tereza do Oeste - PR. The treatments were generated by factorial (2x3)+1+1, being two waste (liquid swine and poultry litter) with three doses of each (poultry litter: 3.3, 6.6 and 9.9 t/ha (wet basis) and pig slurry: 60,120 and 180 m3/ha. Others additional treatments were the control (no fertilization) and mineral fertilization (215 kg/ha of the formulated 08-28-16). Was evaluated the leaf content of nitrogen, phosphorus, potassium, copper and zinc, the lodging, grain yield and oil yield. The data were submitted to variance analysis (ANOVA); the effect and kind of animal waste were evaluated by the Tukey test with 5 % of probability; and the adicional treatments were compared by contrast analysis. The residual fertilizers with animal manure results in crambe plant with bigger leaf content of P and Zn. And also was a bigger percentation of lodging in relation to control and mineral residual fertilization. The grain productivity and oil yeld was equivalent, compared with residual fertilization with animals waste and mineral. / A inserção de crambe (Crambe abyssinica Hochst ex R.E.Fr.) nos sistemas de produção sob sistema plantio direto possibilita o aproveitamento da adubação residual da cultura anteriormente implantada. De modo geral, a oferta de nutrientes às plantas é feita por meio de adubação química e esta representa grande parte dos custos para produção. Uma alternativa para reduzir os custos e fornecer nutrientes de qualidade é por meio da utilização de dejetos de animais. O objetivo do presente trabalho é avaliar o nível de aproveitamento nutricional residual pelo crambe e o seu desempenho produtivo após o cultivo de feijão adubado com diferentes doses de adubação com dejetos de animais e adubação química. A área experimental localiza-se na Estação Experimental do Instituto Agronômico do Paraná, no município de Santa Tereza do Oeste - PR. Os tratamentos foram gerados pelo esquema fatorial (2x3)+1+1, sendo dois dejetos (líquido de suínos e cama de aviário) e três doses de cada (cama de aviário: 3,3; 6,6 e 9,9 t/ha (base úmida) e dejeto líquido de suínos: 60; 120 e 180 m3/ha). Os tratamentos adicionais utilizados foram a testemunha (sem adubação) e o com adubação mineral (215 kg/ha do formulado 08-28-16). Foram avaliados os teores foliar de nitrogênio, fósforo, potássio, cobre e zinco, o acamamento, produtividade de grãos e produtiviade de óleo. Os dados foram submetidos à análise de variância (ANOVA); o efeito do tipo e das doses dos dejetos animais foi avaliado pelo teste de Tukey a 5 % de probabilidade; e os tratamentos adicionais foram comparados por meio de análise de contraste. A adubação residual com dejetos de animais resultou em maior teor foliar de P e Zn em plantas de crambe. Houve um maior percentual de plantas acamadas, em relação à testemunha e à adubação residual mineral. A produtividade de grãos e o rendimento de óleo foram equivalentes, em relação às adubações residuais com dejetos de animais e mineral

Two metabolism trials were conducted with 15 wethers surgically equipped with duodenal and ileal cannulas to study the absorption of P and certain other minerals from swine waste and broiler litter. The effect of source and level of P on rumen cellulytic bacterial populations was also determined. Animals were fed a low P basal diet until serum inorganic P averaged 5.5 mg/dl, then randomly assigned to the following diets: low P basal alone, or supplemented with swine waste, broiler litter, dicalcium phosphate, or soybean meal. Trials consisted of a 7-d preliminary period, a 7-d collection of urine and feces and a 6-d sampling of duodenal and ileal digesta, and feces. Animals fed the waste diets tended to absorb more P than those fed the conventional supplements. Calculated by difference, sheep absorbed more P from swine waste and broiler litter than from dicalcium phosphate and soybean meal (P< .1). Less Ca was absorbed from the waste diets than from the conventionally supplemented diets (P< .05). Expressed as g/d, there was no difference in Mg absorption between waste and conventional diets. Sheep fed waste tended to digest more dry matter and a higher percentage of ADF in the large intestine. Lignin was primarily digested in the large intestine of all sheep. More cellulytic bacteria were isolated from the rumen of sheep fed the supplemented diets (P< .05). Both P intake and P recycling appear to be important influences on cellulytic bacteria in the rumen. Both broiler litter and swine waste appear to be good sources of P and Mg for ruminants. / Ph. D.
